Cohen reportedly signed the document the same day, but there is an empty blank space where 'DD' was supposed to sign, but did not.

Both agreements are appended to the lawsuit as Exhibit 1 and Exhibit 2, the website reports.

Yesterday, it emerged that lawyer Cohen moaned to friends he had not been reimbursed for paying Daniels hush money out of his own pocket.

Last month the attorney said he made the payment and denied it violated any campaign finance laws.

Cohen had been working to secure a deal with Daniels just weeks before the November 2016 US election, it is claimed.

But as the deal was being brokered, it is claimed he was unable to track down Trump for the money forcing him to use his cash instead.

Earlier this year, it emerged that Trump allegedly had the porn star spank him with a Forbes business magazine cover featuring his picture.

In 2009, Daniels was thinking of a run for the Senate in Louisiana and was working with local political consultants about potential donors.

Trump was on her list - and his name was one of the contacts in her phone, one political aide told Democratic consultant Andrea Dubé in an email.

"She says one time he made her sit with him for three hours watching Shark Week. Another time he had her spank him with a Forbes magazine," the consultant wrote to Dubé.

The consultant revealed Daniels had told him the bizarre spanking session occurred while they were involved in a sexual relationship that began soon after they met during a golf tournament in July 2006.

The magazine that Trump asked Daniels to spank him with had his face on the cover, the consultant added.

Responding to the claims Daniels received "hush money" the White House said: "These are old, recycled reports, which were published and strongly denied prior to the election."

The president has repeatedly said that all of the more than a dozen women who’ve accused him of sexual misconduct or assault are liars.

Daniels claims Trump was terrible in bed.

"[The sex] was textbook generic," she said in an interview with US magazine InTouch magazine in 2011.

"It was nothing crazy. It was one position, what you would expect someone his age to do."

The seven-year-old interview was published for the first time earlier this week after allegations emerged that Trump's personal lawyer brokered a deal for her never to speak again.

But before accepting the supposed payment weeks before Trump was elected, the Good Will Humping star had already discussed her alleged liaison with Trump with InTouch.

She and the billionaire businessman met at a celebrity golf tournament in Nevada in 2006 - after Trump had married Melania and when their son, Barron, was just three months old, she said.

Daniels said she agreed to go back to his hotel room, where she says she teased him about his hair and he evaded her questions about Melania.

"He goes, 'Oh, don’t worry about her,'" she recalled.

Eventually, Trump began pressuring her to get closer to him.

"He was sitting on the bed, and he was like, 'Come here.' And I was like, 'Ugh, here we go,' and we started kissing," she said.

"I actually don’t even remember why I did it, but I do remember while we were having sex, I was like, 'Please don’t try to pay me.' And then I remember thinking, 'But I bet if he did, it would be a lot,'" she said, according to the mag.

Afterward, he asked her to sign a copy of her X-rated film 3 Wishes, Daniels said.

She said the now president became "smitten" and started calling her every 10 days, promising to get her on The Apprentice and referring to her as "honeybunch", she said.

She also recalls Trump comparing her to his daughter, Ivanka.

"He told me once that I was someone to be reckoned with, beautiful and smart just like his daughter,"Daniels said.

Despite the then-60-year-old Trump’s unremarkable performance between the sheets, the pair continued to meet up, including in his office at Trump Tower in 2007.

"Whether you’re a fan of his or not, which I never really was, you gotta admit he's pretty fascinating," she said of their relationship.
